Description
VAST (Video Ad Serving Template).
It's a XML standard response which contains all the information the Ad Server has to show inside a video player. This response was standardized by the IAB, to make the Ad server always communicate the same way with the player. It's mandatory that the player support this technology and can read the information e-planning gives in the XML properly. There are different VAST's formats:
- Lineal: Inside the player, the Ad may be before, after or during the video content (preroll, midroll, postroll).
- Non-Lineal: Outside the player, the Ad plays at the same time than the video content. Users will see it while seeing the video content. Non-lineal Ads may be delivered as text, graphic Ads, or static images (overlay, companion).
